Review-ready Target Rationale

Why Adrenergic receptor alpha-2 matters

As of 2026-09-13

Adrenergic receptor alpha-2 is reviewed as Alpha-2A adrenergic receptor (UniProt P08913); Adrenergic receptor alpha-2 shows approved-linked disease relevance led by hypertension. 5 more disease programs remain visible in the same review block.; 5 linked drugs keep this evidence frame grounded.; the current evidence base includes 29 approved drugs, 495 compounds, and 230 assays, with lead potency reaching pChEMBL 10.8.

Protein context
Alpha-2A adrenergic receptor

Alpha-2A adrenergic receptor Sequence length is 465 aa.

Review this target as Adrenergic receptor alpha-2, mapped to UniProt P08913. ChEMBL maps the protein component as Alpha-2A adrenergic receptor. Sequence length is 465 aa.

Disease context
hypertension

Adrenergic receptor alpha-2 shows approved-linked disease relevance led by hypertension. 5 more disease programs remain visible in the same review block. 5 linked drugs keep the rationale reviewable. 5 additional disease programs remain visible in the same card. Linked drugs include BRIMONIDINE TARTRATE, CLONIDINE, CLONIDINE HYDROCHLORIDE.

Start review with hypertension because it currently carries approved-linked support. Linked drugs include BRIMONIDINE TARTRATE, CLONIDINE, CLONIDINE HYDROCHLORIDE, GUANFACINE HYDROCHLORIDE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
